My understanding is that the 11-13 inch fish are next years mature kokes. Earlier this year almost all of my catch were 15-18 inch fish from Lucky Peak. Now those fish are few and far between. In my experience, this immature class of fish does not become aggressive towards our lures until midsummer the year before they spawn. Kokanee are plankton feeders and hit our lures more out of aggression then as a food source. It could be that we have a large number of "jack" this year and they will try to spawn before they are mature. Not sure if kokanee have a tendency to try to spawn early, but several other salmon species are known to do so.
